Worst Service Ever!

We had booked return taxi transfers with Click Transfers from & to Antalya airport in Turkey due wanting no fuss travel, but we ended up getting the most difficult transfers ever.
On arrival at Antalya airport at approx. 00:15 on the 12th July there was no one with an Oxygen travel board as stated there would be. We went to all the desks asking for help to be sent back to arrivals to look for a resort hopper board. We were then sent to desk 26 who made a phone call and told us we should be at desk 19 but they had gone home. We then went back to resort hopper who then told us to stand with this large group of people with no explanation. All the coach transfers had gone by this point. We were then shuttled to another area and gradually we all had to wait for a taxi to arrive where a man would family by family put us into a taxi. The taxi did not have a middle seatbelt for my son & the driver just kept banging his dash angrily all the way to the hotel as the petrol gauge did not work. He was overtaking cars at junctions when the lights were on red leaving us sticking out in the road. When we finally arrived we realised with all the commotion we had only 2 of our 3 suitcases. I then had to get a translator to ring the airport and then get back to the airport for our suitcase & returned finally to the hotel at approximately 6am.

For the return transfer we were requested to ring a number to confirm the pick up time. The day before departure I tried for two hours solidly and then on & off all day. I contacted clicktranfers to try and help arrange a time who stated they would ring me when they got a time. It was 40 degrees and I could not even go in the pool all day in fear of missing the call. They never rang back so at approximately 5pm English time I contacted them again to be told that it is not their job to arrange this but mine and that they had spoke to the agent & I had not confirmed my return and that the phone line was clear now & I should ring them again. I think that it is totally unsatisfactory that they should be stating that I had not called the office when their phone lines have been dead for most of the day. This had totally ruined this day of the holiday for us. I paid for my transfers directly with clicktransfers and so would assume that they would deal with problems such as these, especially after stating that morning that they would.
We booked a taxi rather than a shuttle to make our lives easier, particularly as I have an autistic son who finds it hard queuing and waiting around. The service we had received has been diabolical. We go abroad on many occasions and this has been the worse experience ever.
I also made a letter of complaint to Clicktransfers 3 day's ago & have still not had a reply.
